Hi team,

Could you provide the following exam code?

1. Online upgrade through serial port. The goal is to upgrade the program for 280039.

    There is an external flash with SPI interface, and the external communication is SCI.

2. Read and write external Flash through SPI

Thanks!

    Hello Kailun,

    In C2000Ware, there is an example Flash kernel provided to support updating firmware in internal Flash memory using an SCI bootloader. This is flash_kernel_ex3 in the driverlib/f28003x/examples/flash directory.

    We do not provide any example code for reading an external SPI Flash, but you can look at the existing SPI examples to understand how to use the SPI module for such communication.

    Best regards,
    Ibukun
